A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?
3000 mg.
3300 mg.
3600 mg.
3750 mg.
The Correct Answer is D
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for 150 mg/kg/day. So, the total daily dosage is 150 mg/kg/day × 25 kg = 3750 mg/day.
So, the correct answer is, after analysing all choices, the nurse should administer 3750 mg of cefotaxime each day.

Correct Answer is ["A","B","C"]
Explanation
Choice A rationale:
Ibuprofen 400 mg every 4 to 6 hours as needed for temperature greater than 100.5 °F (38 °C). This order is questionable because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can potentially increase blood pressure, which could be harmful to a patient with hypertension. Furthermore, NSAIDs can mask the symptoms of infection, which could delay the diagnosis and treatment of serious infections.
Choice B rationale:
Enalapril 10 mg every morning. This order is questionable because enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. However, ACE inhibitors can cause a dry cough, which could exacerbate the patient’s existing cough due to pneumonia. Additionally, ACE inhibitors can potentially cause hyperkalemia (high potassium levels), so it’s important to monitor the patient’s electrolyte levels.
Choice C rationale:
Supplemental oxygen 10 L/min via nasal cannula. This order is questionable because a high flow rate of oxygen can potentially cause oxygen toxicity or hyperoxia, which can lead to cellular damage. The typical flow rate for a nasal cannula is between 1-6 L/min. A flow rate of 10 L/min may be too high for this patient, especially without a specified target SpO2 range.
Choice D rationale:
Continuous pulse oximetry. This order is appropriate because it allows for continuous monitoring of the patient’s oxygen saturation levels, which is crucial in a patient with pneumonia and shortness of breath.
Choice E rationale:
Send blood for a complete blood count, electrolytes, blood cultures, and procalcitonin. This order is appropriate because these tests can help monitor the patient’s overall health status and response to treatment.
Choice F rationale:
Admit to the medical floor. This order is appropriate because the patient requires hospitalization for treatment and monitoring due to his pneumonia.
Choice G rationale:
Vital signs every 4 hours. This order is appropriate because it allows for regular monitoring of the patient’s vital signs, which can help detect any changes in his condition.
Choice H rationale:
Chest x-ray now. This order is appropriate because a chest x-ray can help confirm the diagnosis of pneumonia and assess its severity.
Choice I rationale:
Sputum culture and sensitivity. This order is appropriate because it can help identify the specific organism causing the pneumonia and determine its antibiotic sensitivity, which can guide antibiotic therapy.
Choice J rationale:
Levofloxacin 500 mg intravenously every 24 hours. This order is appropriate because levofloxacin is a broad-spectrum antibiotic commonly used to treat pneumonia.
Correct Answer is B
Explanation
Choice A rationale:
The statement, "This medication will help regulate my mood and anxiety," is an accurate description of how antidepressants work. Antidepressants can help improve mood and reduce anxiety symptoms over time.
Choice B rationale:
This is the correct answer. Expecting immediate results from antidepressant medication is a misunderstanding. Antidepressants typically take several weeks to show their full therapeutic effects. Clients need to be informed about the delayed onset of action.
Choice C rationale:
The statement, "I may experience side effects such as nausea and drowsiness," is accurate. Antidepressants can indeed cause side effects, including gastrointestinal symptoms like nausea and drowsiness. This information is essential for the client to be aware of.
Choice D rationale:
This statement is correct. It is crucial to take antidepressant medication consistently as prescribed for the best therapeutic outcomes. Stopping or missing doses without consulting a healthcare provider can lead to treatment ineffectiveness.
